The bids have now been sent for technical bid evaluation which may take a few months to complete. When this is done, the financial bids of the technically qualified bidders will be opened to identify who is the lowest bidder and most likely contractor.

The assigned contractor will have to use at least 4 Tunnel Boring Machines (TBMs). The DC-05’s design details such as crossover and ramp locations can be seen here.


DMRC has publicly posted that they are pursuing the June 2024 deadline to start operations on the 28.92 km extension of the Magenta Line between Janakpuri West – RK Ashram. This construction will not be possible due to practicalities and I think this section is not opening before mid 2026 at this time.

With this development, technical bids have been opened for all 4 JICA-funded underground packages of Phase 4. I believe that by the end of the year, if possible, we will start opening financial bids in November with the award of construction contracts.
